Ultra Deep Hubble Field Skywalker v1.0

[pokerfan]

Within the Hubble Ultra Deep Field there are approximately 10,000 discrete objects. The total field of view represents only one ten-millionth of the total sky. The full image mosaic is a 60MB download and won't display on your machine unless you have at least 110 megs of free RAM.

Fortunately, we have the UDF Skywalker server:



Click-drag green circle to pan around the whole image. The Ultra Deep Field obtained by the Hubble Space Telescope is the deepest view into the sky by humankind to date. This image combines 800 frames with a total exposure time of 1 million seconds. The 10.000 galaxies that are visible have distances out to times where the universe was just 800 million years old, one seventeenth of its current age.

3. Space is really big

The total field of view represents only one ten-millionth of the total sky.

To help put this in perspective for me, I calculated that the field of view of the entire UDF is like viewing a standard sized postage stamp from a distance of sixty feet. Holy crap.

Another "fact" that I hear often: there are more stars than there are grains of sand on all the beaches in all the world combined. I had to check that out too.

Thirty to seventy billion trillion stars in the observable universe:

Seven quintillion five quadrillion grains of sand:

3x10²² stars >> 7.5x¹⁸ grains

More stars than sand grains by several orders of magnitude.

4. You just won't believe how vastly hugely mindboggingly big it is.

"Space," it says, "is big. Really big. You just won't believe how vastly hugely mindboggingly big it is. I mean you may think it's a long way down the road to the chemist, but that's just peanuts to space."

9. Yep!

I'm going to the beach in a couple days!

Hope the Vogons stay away.

6. It would seem egotistical to think that we are alone in this univers. eom
